Abstract
For use in a floating-point unit that supports floating-point formats having fractional parts of varying widths and employs a datapath wider than the fractional parts, a circuit and method for normalizing and rounding floating-point results and processor incorporating the circuit or the method. In one embodiment, the circuit includes: (1) left-shift circuitry for aligning a fractional part of the floating-point result with a most significant bit of the datapath and irrespective of a width of the fractional part to yield a shifted fractional part and (2) rounding circuitry, coupled to the shift circuitry, that rounds the shifted fractional part.
